To all whom it may concern:

Be it known that I JOHN Fons'rnn, a citizen of the United tates, residing at Los An eles, in the county of Los Angeles, State of alifornia, have invented new and useful Improvements in Pencil Attachments, of which the following is a specification.

llhis invention relates to a pencil attachment.

lit is the object of this invention to provide,

an attachment for lead pencils embodying a metallic stylus or marking point which which may be readily applied to or removed I from the lead pencil and which will serve as a pocket engaging clip when the stylus is in its inoperative ositlon.

The invention is i ustrated in the accompanying drawing, in which:

Figure 1 is a view in side elevation of the lead pencil showing the invention as applied, and with the stylus in its folded position. Fig. 2 is a similar view showing the opposite side of the lead pencil with the attachment thereon. Fig. 3 is an edge view as seen in the direction indicated by the arrow 3 in Fig. 2. Fig. 4=is a detail horizontal sectionand elevation as seen on the line 4.-4 of Fig. 2 in the direction indicated by the arrow. Fig. 5 is a view in elevation of the lower portion of the lead pencil showing the attachment with the stylus point disposed in its operative position.

More specifically, 6 indicates the body portion of the device which is tubular in form and adapted to receive the end of a lead pencil 7. The tubular member 6 is formed of metal and is divided longitudinally on one side thereof as indicated at 8 in Figs. 3 and 4 so as to render the body member 6 of a resilient character and permit its being expanded in inserting the pencil 7 therein; the side portions of the sleeve members 6 forming spring clips adapted to frictionally engage the pencil 7.

Encompassing one end of the sleeve member 6 1s a yoke 9, the opposite arms of which are secured to the sleeve members 6 by a pivot pin 10 which extends across the interror of the sleeve 6 and forms a stop for limitlng the inward movement of the sleeve on the end of the pencil 7. One of the arms of the yoke 9 is formed with a transversely extendmg convergent portion 11 terminating n a stylus point 12 which normally projects In the du ect1on of the length of the sleeve 6 and pencil 7.

The yoke 9 is adapted to be turned on its plvot pm 10 to position the portion 11 and stylus point 12 so that they will extend along the sleeve member 6 as shown in Fig. 1; the stylus point 12 being then folded into aninoperative position. The outer ends of the arm portions of the yoke 9 are curved at 13 and 14: to extend over the edge of the sleeve member 6 into engagement with the latter as shown in Fig. 4, when the stylus point 12 extends in either direction longitudinally of the member 6; the bent portions 13 and 14 forming tongues which cooperate with the connection portion 15 of the yoke 9 in enga g the opposite sides of the sleeve mem er 6 to normally hold the yoke against too free rotation.

.The connecting portion 15 of the yoke 9 serves to limit the pivotal movement of the yoke 9 in either direction; the connecting portion 15 abutting against the sides of the sleeve member6when the stylus is disposed in either its open or closed position.

In the application and operation of the invention, the s'leeie member 6 is placed on the lead pencil 7 adjacent the end of the latter with the stylus point 12 extending alongside of the sleeve member 6 when it is not in use. When it is desired to use the stylus 12 the yoke 9 is rocked to position the stylus with its point projecting beyond the end of thepencil as shown in Fig. 5 whereupon the stylus may be drawn across. the surface to be marked in the'direction indicated by the arrow a. lhe connecting portion 15 of the yoke in abutting against A the edge of the sleeve member 6 will serve to prevent rotation of the yoke in the direction of the pressure imposed on the stylus 12.

The tongues 13 and 14; will cooperate with the connecting portion 15 of the yoke to hold the latter against free rotation; the tongues 13 and 14: riding out of en agement with the edge of the sleeve mem er 6 on pressure being applied to the member 14 normal folded position.

through said yoke and said sleeve pivotally securing the yoke to the sleeve for extension of said stylus longitudinally of the sleeve in either direction and for limiting the movement of the stylus in either direction.

In witness that I claim the foregoing I have hereunto subscribed my name this 29th day of October, 1914.
